Application September 29, 1949, Serial No. 118,502

1 Claim. 1

My invention refers to bottle caps and it has for its object to provide a cap that can easily be removed by manipulating an attached key complementary to each cap, whereby separable bottle cap openers are dispensed with.

The specific object of my invention is to prov1de a cap having ears engaging the slotted stem of a key, the ears being partially wound about the key to retain the same as an integral capped member. Hence, when the cap is to be removed, it is rotated, whereby the ears or ear is broken or stripped, together with a section of the cap to mutilate said cap in such manner that it can be readily removed from its position about the bead of the bottle mouth.

Thus, each cap carries a self contained key opener to avoid the inconvenience of a separable bottle opener which may not be available.

With the above and other objects in view,

which will appear as the description proceeds,

the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 represents a side elevation of a bottle neck equipped with a cap embodying the features of my invention, the same being partly in section as indicated by line I, l of Figure 2.

Figure 2 is a plan view of the same.

Figure 3 is a sectional elevation; the section being indicated by line 33 of Figure 1.

Figure 4 is another elevation, partly in section, illustrating the cap wound upon the key and partly removed from the mouth bead of the bottle.

Figure 5 is a plan view of a flat cap blank having a flanged portion for ears extending therefrom.

Figure 6 is a side elevation of another form of cap and key, the same being partly in section as indicated by line 6, 6 of Figure '7.

Figure 7 is a planned sectional view of the same, the section being indicated by line I, l of Figure 6; and

Figure 8 is a similar plan sectional elevation 2 illustrating the key in folded engagement with the single tongue.

Figure 9 is a plan view of the blank cap, the flanged portion of which is interrupted and tangentially provided with a single tongue.

Referring by characters to the drawing, A indicates a bottle neck, the mouth of which is provided with the usual bead B. Fitted to the mouth bead is a metallic cap I, having a downturned crimped flange l, which flange is provided with a pair of ears 2, '2' that are lapped or folded upon each other, as best shown in Figures 2 and 3 of the drawings.

The lapped end of the ears pass through a slot 3 of a key stem 3', having a downturned handle portion that laps the cap B after the key is properly positioned. It may be in some cases slightly twisted to cause the ends of the tongues to coil about the key stem, whereby said key is confined to the cap.

As shown in Figure 5 of the drawings, a flat view of the cap is illustrated having a flanged edge I from which flange a pair of ears 2, 2, the same being diametrically opposite each other.

Hence, when the cap is crimped upon the bottle mouth, its flange is folded over the bead of said mouth and the ears are folded and lapped upon each other about the face of the cap, as shown in Figure 2. Hence, in order to remove this cap, all that is necessary is that the key be rotated so as to wind or coil the tongues upon it and said key is given the required number of rotations, whereby the ears and capped body are partially broken away or mutilated, whereby the cap may readily be removed.

Referring to Figures 6 and 8 inclusive, I have illustrated another form of my invention wherein the cap flange l" is mutilated and one edge of the mutilated cap flange has tangentially projecting therefrom a tongue 2", as best shown in Figure 9 of the drawings.

After this cap is crimped over the bead of a bottle mouth, as shown in Figures 6 to 8 of the drawings, the ear 2 is threaded through a slot 3" of the key, which key is positioned vertically or in parallel relations to the capped flange I. Hence, when it is desired to remove the cap, the key is simply rotated as indicated in Figure 8 of the drawings, whereby continuous rotation of said key will cause the ear and its associated flange to be broken away from the cap body, whereby said cap can readily be removed.

I claim:

A bottle cap of the type having a flange adapted to be crimped over the mouth head of a bottle comprising, a pair of ears extending from the lower periphery of the flange and positioned diametrically opposite one from the other, each ear extending upwardly conforming to the contour of the flange and thence over the top portion of the cap, the outer ends of said ears terminating in an overlapped relation, and a key having a slot therein for receiving the overlapped ends of the ears, whereby upon rotation of the key said ears will be wound upon the key to pull the respective'portions of the flange upwardly and thereby release the cap from the bottle.
